摘要:
A receiving antenna with a rigid directional pattern, that is to say with an anisotropic receiving sensitivity of the receiving antenna, is used for localizing a wheel electronics unit in a wheel of the motor vehicle. Suitable evaluation of the received electromagnetic signals is provided in order to obtain a functionality achieved by way of the displacement or rotation of the directional antenna in the case of prior solutions. In this respect, a level of the received electromagnetic signal is compared with a predefined threshold value. As the result of the comparison, the wheel electronics unit is localized as being arranged in a wheel of the first wheel group or as being arranged in a wheel of the second wheel group.

In the method according to the invention and the arrangement or according to the invention for extracting extraction products in underground mining operations using the caving method, the extraction products (20) collapsing in an upper gate area (10) are extracted via at least one extraction funnel (13) or the like into an extraction path (14) driven below the gate and are transported away therein by means of an extraction conveyor (15). According to the invention the extraction funnels (13) are arranged laterally beside the extraction conveyor (15) and lead at their lower end into a ramp surface (17) inclined towards the extraction conveyor, the extraction products extracted from the gate through the extraction funnels being transported slidingly over the inclined ramp surface to the extraction conveyor. The inclined ramp surface is preferably formed by a loading ramp (22) which is so arranged in an extraction chamber (16) branching off laterally from the extraction path that its one end (19), disposed higher, is located below the extraction funnel and its other end (23), disposed lower, forms an outlet (21) towards the extraction conveyor.

In a mass flow sensor having a layered structure on the upper side of a silicon substrate (1), and having at least one heating element (8) patterned out of a conductive layer in the layered structure, thermal insulation between the heating element (8) and the silicon substrate (1) is achieved by way of a silicon dioxide block (5) which is produced beneath the heating element (8) either in the layered structure on the silicon substrate (1) or in the upper side of the silicon substrate (1). As a result, the sensor can be manufactured by surface micromechanics, i.e. without wafer back-side processes.

A device for separating impurities from liquids has at least one separating container for separating impurities from a liquid/impurities mixture flowing in a flow direction through the at least one separating container. A partition divides the interior of the at least one separating container. At least two separating elements are arranged sequentially in the flow direction within the separating container, wherein the at least two separating elements have different diameters parallel to the partition.
摘要:
A method for anodic bonding of wafers and a device essentially composed of such bonded wafers. An intermediate layer is placed between two wafers, after which the two wafers are anodically bonded. The method and the device have the advantage of being implementable and manufacturable, respectively, in a particularly cost-effective manner. The anodically bonded intermediate layer plastically encloses any possible particles present or evens out differences in height of the wafer surfaces to be bonded and thus prevents any extensive bond defects from occurring.

The present invention relates to a conveyor pan (50) for underground face and gate conveyors, with a bottom pan (2) and a top pan (3) for the guidance of scrapers of a scrapper chain, the conveyor pan (50) having a welded frame construction (1) comprising side walls firmly fixed to one another with a conveyor base (8) and a means (60) of joining the conveyor pans. In accordance with the present invention the side walls comprise mirror image single part rolled profiles (10) with a constant profile form over the length of the conveyor pan (50), whereby the rolled profile (10) includes a base arm (11) and a top arm (12) both angled outwards as well as an extended intermediate arm (13) joining these, which is provided with an offset (14), onto which intermediate arm (13) on its inside at least one step (17) is formed for the support and welding on of at least one of the intermediate plates (40A) stiffening the frame construction (1).
摘要:
Soft-tipped airway exchange apparatus for use when replacing an endotracheal tube in a patient with a new endotracheal tube. The apparatus comprises a polymeric catheter body sized for insertion into a passageway of the endotracheal tube, for ventilating the patient during replacement of the endotracheal tube. The catheter body has a proximal portion, a distal portion and a ventilation passageway extending longitudinally therein. The distal portion has a rigidity which is less than the rigidity of the proximal portion.
摘要:
A micromechanical structural element, having a very stable diaphragm, implemented in a pure front process and in a layer construction on a substrate. The layer construction includes at least one sacrificial layer and one diaphragm layer above the sacrificial layer, which is structured for laying bare the diaphragm and generating stabilizing elements on the diaphragm, at least one recess being generated for a stabilizing element of the diaphragm. The structure generated in the sacrificial layer is then at least superficially closed with at least one material layer being deposited above the structured sacrificial layer, this material layer forming at least a part of the diaphragm layer and being structured to generate at least one etch hole for etching the sacrificial layer, which is removed from the region under the etch hole, the diaphragm and the at least one stabilizing element being laid bare, a cavity being created under the diaphragm.
摘要:
A delivery device for placing an implant or prosthesis inside a body is described. The device is useful for placing a variety of stents or implants when used with a cystoscope or other visualization or placement device. An inner sheath is relatively stiff and an outer sheath is relatively pliable or soft compared to the inner sheath. The sheaths are assembled to a connector and a positioner is then inserted through the center of the assembly, the inner sheath. The implant is placed near the distal end of the outer sheath, and the assembled device with the implant is backloaded onto a cystoscope or endoscope for placement. The inner sheath may be used to tailor the stiffness or rigidity of the assembled delivery device.
